Oral Mucosal Lesions in Patients Attending Dermatology Outpatient Department of a Tertiary Care Center in Kathmandu: A Descriptive Cross-sectional Study.

INTRODUCTION: Oral mucosal lesions though mostly benign, may impair the quality of life of patients. Some may even progress to malignancies. Many physicians, including dermatologists, tend to skip oral examinations, missing many important diagnoses. Understanding the frequency and types of oral mucosal lesions in dermatological settings can help in early diagnosis, referral and adequate treatment. This study was done to determine demographic characteristics and clinical presentations of patients with oral mucosal lesions presenting to the out-patient department (OPD) of dermatology in Nepal Armed Police Force (APF) Hospital, Kathmandu. METHODS: This cross-sectional descriptive study was conducted after obtaining the ethical approval from the Institutional Review Committee of Nepal APF Hospital. Retrospective data of 264 patients presenting with oral mucosal lesions to the dermatology OPD were collected from 1st January 2021 to 31st December 2023 by using a pre-formed proforma. Data was entered in SPSS software and descriptive statistics were computed. RESULTS: Out of 13,832 cases, oral mucosal lesion was seen in 264 (1.90%) cases among which 153 (57.96%) cases were males with male female ratio of 1.37:1. Most common age group affected was 31-45 years 96 (36.36%). Buccal mucosa 86 (32.57%) was the commonest site involved followed by tongue 73 (27.65%). Aphthous ulcer 82 (31.06%) was the commonest lesion found followed by oral candidiasis 25 (9.46%) and oral lichen planus 24 (9.09%). CONCLUSIONS: Aphthous ulcer was the commonest oral mucosal lesion seen in patients visiting dermatology outpatient department of Nepal APF Hospital, with buccal mucosa being the commonest site affected.

Proportion Of vitiligo and associated factors among patients visiting dermatology opd in tibebe ghion specialized hospital and addisalem primary hospital, bahirdar city, Ethiopia,2023.

OBJECTIVE: This study aimed to determine the prevalence of vitiligo and associated factors among patients visiting the dermatologic outpatient departments at Tibebe Ghion Specialized Hospital and Addisalem Primary Hospitals, Bahir Dar, Ethiopia, from September 15 to November 15, 2023. RESULTS: Among the 460 patients studied, 243 (52.8%) were female, with the majority (28.9%) aged between 25 and 34 years. The overall prevalence of vitiligo was found to be 7.4% (34 patients). Significant predictors of vitiligo included rural residence (AOR: 3.18; 95% CI: 1.10-9.18), family history of vitiligo (AOR: 2.20; 95% CI: 2.16-4.76), and aggravating factors such as trauma (AOR: 1.08; 95% CI: 1.01-2.08). The highest prevalence was observed in the 14-24 age group. These findings suggest the importance of awareness campaigns focusing on the causes, symptoms, and treatments of vitiligo, particularly among young adults in rural areas.

Trends in Dermatological Diagnoses During Covid-19 Pandemic in Nigeria: A Retrospective Study.

INTRODUCTION: Coronavirus disease (COVID-19) quickly became a pandemic causing a global concern affecting public health directly and indirectly. Dermatology outpatient services were not an exception to the impact of COVID-19, especially in Sub-Saharan Africa. To the best of our knowledge, no similar study has been done in this region, and identifying patterns of dermatological diseases would help prepare adequately for future crises. OBJECTIVE: This study examined the changes in diagnostic patterns at the dermatology clinic before the COVID-19 pandemic and during the pandemic. METHODS: This retrospective study was conducted on dermatology outpatients seen at Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria. Diagnoses were compared during the pandemic (March to August 2020) with the corresponding period of the previous year. RESULTS: A total of 534 patients with 559 diagnoses were included. The average weekly dermatology clinic visits remained unchanged during the pandemic, although there was a 25.8% reduction in dermatology outpatients. The most common reasons for visiting the outpatient clinic during the COVID-19 pandemic were acne vulgaris, scabies, atopic dermatitis, dermatophytosis, and pityriasis versicolor. While the percentage of scabies significantly decreased during the pandemic; the percentage of allergic contact dermatitis, prurigo nodularis, candidiasis, hemangioma, and lupus erythematosus increased respectively. CONCLUSION: Although the COVID-19 pandemic had a negligible impact on the average weekly number of skin clinic visits, it caused a change in diagnostic patterns. Understanding the pattern of skin diagnoses may help hospitals better prepare for future pandemics.

INTRODUCTION: La maladie à coronavirus (COVID-19) est rapidement devenue une pandémie suscitant une préoccupation mondiale, affectant directement et indirectement la santé publique. Les services ambulatoires de dermatologie n'ont pas échappé à l'impact du COVID-19, en particulier en Afrique subsaharienne. À notre connaissance, aucune étude similaire n'a été réalisée dans cette région, et l'identification des tendances des maladies dermatologiques permettrait de se préparer adéquatement pour les crises futures. OBJECTIF: Cette étude a examiné les changements dans les tendances diagnostiques à la clinique de dermatologie avant et pendant la pandémie de COVID-19. MÉTHODES: Cette étude rétrospective a été menée sur des patients ambulatoires de dermatologie vus à l'hôpital universitaire d'enseignement Nnamdi Azikiwe, Nnewi, au Nigeria. Les diagnostics ont été comparés pendant la pandémie (mars à août 2020) avec la période correspondante de l'année précédente. RÉSULTATS: Un total de 534 patients avec 559 diagnostics ont été inclus. Le nombre moyen de consultations hebdomadaires à la clinique de dermatologie est resté inchangé pendant la pandémie, bien qu'il y ait eu une réduction de 25,8 % des patients ambulatoires de dermatologie. Les raisons les plus courantes de consulter la clinique ambulatoire pendant la pandémie de COVID-19 étaient l'acné vulgaire, la gale, la dermatite atopique, la dermatophytose et le pityriasis versicolor. Alors que le pourcentage de gale a diminué de manière significative pendant la pandémie, le pourcentage de dermatite de contact allergique, de prurigo nodulaire, de candidose, d'hémangiome et de lupus érythémateux a augmenté respectivement. CONCLUSION: Bien que la pandémie de COVID-19 ait eu un impact négligeable sur le nombre moyen hebdomadaire de consultations à la clinique de dermatologie, elle a entraîné un changement dans les tendances diagnostiques. Comprendre les tendances des diagnostics de peau peut aider les hôpitaux à mieux se préparer pour les futures pandémies. MOTS CLÉS: COVID-19, patients ambulatoires de dermatologie, diagnostics dermatologiques, Afrique de l'Ouest, Nigeria, tendances.

Inter-institutional Analysis of Skin of Color Representation in Dermatological Lecture Content at MD and DO Medical Schools.

INTRODUCTION: The purpose of this study was to analyze the lecture materials provided in medical schools through a diversity lens. Skin pathologies manifest distinctively on various shades of skin and physicians must be equipped with the proper knowledge to identify and diagnose these conditions accurately and promptly. For most medical students, images in prominent textbooks and lecture slides are their first encounter with disease presentations. Therefore, it is important to analyze the diversity of skin tones in the content that is being delivered. Specifically, the use of images featuring darker skin tones compared to those depicting lighter skin tones. METHODS: This study analyzed lecture materials from two allopathic and two osteopathic medical schools. The analysis was limited to lectures given during the Skin/MSK block or dermatology block. The skin pathologies were organized into five categories: Inflammatory Disorders, Infectious Skin Disorders, Pigmented Disorders, Non-Pigmented Disorders, and Blistering Disorders. Images were classified as dark skin tones, light skin tones, and indeterminate based on the Fitzpatrick Scale. RESULTS: The results showed that of the 560 images analyzed: 96 images, or 17.14%, were representative of dark skin tones, 78.04% were representative of light skin tones, and 4.82% were classified as indeterminate. CONCLUSIONS: A potential outcome of this study involves bolstering medical education in the United States by exposing medical students to a more diverse set of exemplary images during their didactic education. In doing so, medical students will be better prepared to provide high quality healthcare to all patients regardless of ethnicity.

Developing and evaluating a mobile-based teledermatology system for skin lesion diagnosis in Iran.

Asynchronous teledermatology (TD) has shown promise in improving access to dermatological care, yet studies reveal varied methodologies and results. This study aimed to design a mobile app using the store-and-forward model, marking a pioneering effort in Iran to facilitate written documentation of patient history and skin lesion imagery for accurate diagnosis. Conducted from July 2022 to July 2023, this study involved the development and implementation of a smartphone app to collect clinical data and photographs from 89 patients at a dermatology clinic. Diagnoses made at the clinic served as the gold standard. Three dermatologists independently reviewed the app-recorded data, providing diagnoses that were compared to in-person assessments using the Kappa coefficient and agreement percentage. Lesions were predominantly located on the whole body (47%), with psoriasis (19.1%), acne vulgaris (11.2%), and eczema (10%) being the most common. The overall inter-observer Kappa value demonstrated excellent agreement at 0.856. The study's findings endorse the use of a mobile app for TD as an effective adjunct in regions with scarce dermatological services, such as Iran. To promote the broader application of TD, ongoing research is essential to further establish its reliability and practicality.

Clinical and Pathological Features of Primary Cutaneous Lymphomas in Nepal: A retrospective cohort study from a dermatology referral centre.

Background Primary cutaneous lymphomas (PCLs) are rare diagnoses in Nepal and are not well characterized till date. Objective To evaluate clinical and pathological features of Primary cutaneous lymphomas in Nepal. Method We retrospectively reviewed outpatient and inpatient records of a dermatology referral centre of Kathmandu, Nepal for clinical and pathological findings of cases diagnosed as cutaneous lymphomas from July 2010 through July 2020. The final diagnosis was made based on 2008 World Health Organization classification and its update 2018. Result There were 12 cases of Primary cutaneous lymphomas diagnosed during this period. The age of presentation ranged from 19 years to 81 years (Mean: 53.4 years ± 21.5 years, SD). There were ten cases of cutaneous T-cell lymphoma (CTCLs) and two cases of cutaneous B- cell lymphomas (CBCLs). Among cutaneous T-cell lymphoma, there were four cases of primary cutaneous anaplastic large- cell Lymphoma (PCALCL), two cases of classic (patch/plaque) mycosis fungoides (MF), two cases of folliculotropic mycosis fungoides (FMF), and one case each of primary cutaneous aggressive epidermotropicCD8+ T-cell lymphoma and lymphomatoid papulosis. Among cutaneous B- cell lymphomas, there was one case of primary cutaneous marginal zone B- cell lymphoma, and one case of primary cutaneous follicle centre lymphoma. Most cases of MF presented at stage IB (75%), and three patients of primary cutaneous lymphomas died during this period. Conclusion Primary cutaneous lymphomas appear to be very rare in this study and presentations ranged from classic Mycoses Fungoides to aggressive T-cell lymphomas. Cutaneous T-cell lymphomas appeared to be more common than cutaneous B- cell lymphomas in this study.
